I don't know if this is a coincidence or not. I have 1.4.8 clients
that does not behave against a 1.4.2 (yeah, I know...) server:

Mar 11 13:21:18 a03c11n14 kernel: afs: Waiting for busy volume 537086116 (prj.sbc.aronh.13) in cell pdc.kth.se

Mar 11 13:39:38 a03c11n14 last message repeated 4 times

Then silence.

Console said something like:
	Call Trace: ... system_call+0x7e/0x83
	.... do_sys_open+0x5c/0xbe
.. Kernel panic - not syncing: Fatal exception

As this is (eh, was) a parallell job several but not all clients
involved did crash like this. Unfortunately, I have no way how to
repeat. I have moved the volume to a 1.4.8 server to start with.
